## Use Cursor-Based Pagination Instead of OFFSET
OFFSET-based pagination scans all skipped rows, getting slower on deeper pages. Cursor pagination is O(1).
**Incorrect (OFFSET pagination):**
```sql
-- Page 1: scans 20 rows
select * from products order by id limit 20 offset 0;
-- Page 100: scans 2000 rows to skip 1980
select * from products order by id limit 20 offset 1980;
-- Page 100
